Would this be one of the better Road Race Specific 6 Speeds?

[tyoneal]

To All:

I am looking at upgrading to a 6 Speed Gearbox because the engine I am putting in the car will far surpass the torque rating of the current transmission.

Since I intend to Track the Car a fair bit, I was looking for a close ratio transmission. Here is what I found:
======================================
http://www.sdparts.com/product/RG705...sionFBody.aspx

The Richmond Six Speed overdrive transmission was designed with the driving enthusiast in mind. The six speed transmission is made in the U.S.A. by American Craftsmen using the latest CNC machining and in house heat treat. Based on our bullet proof five speed design, the Richmond ROD has another gear-to-grab overdrive!

Note: Includes cross member, speedo cable extension and special shifter for torque arm hook up.
Gear Ratios: 3.27 / 2.13 / 1.57 / 1.23 / 1.00 / 0.76
=======================================

I am going to follow up on the internals, however the gear ratios appear to be more suited for RR.

=======================================
I also like this one from ATS:

LSX T-56 six speed
LSX style T-56 six speed transmission with Viper internals $3,600.00

View Enlarged ImageTremec T-56 six speed manual transmissions are one of the most popular swaps into muscle cars today. American Touring Specialties now offers a bolt in T56 for your LSX conversion capable of handling the power levels of modified LS7 engines, and the extreme abuse associated with road racing. We begin with a brand new LS1 T-56 from the 98-02 Camaro/Firebird vehicles and completely disassemble and upgrade the internals of the case. This upgrade includes triple cone syncros made of Kevlar, a steel 3/4 shift fork, and a heavy duty Viper output shaft capable of handling up to 750 ft lbs of torque. the entire transmission is reassembled with precise tolerances, and blueprinted to ATS specifications. the units include a factory cast aluminum bellhousing, case to bellhousing bolts, all electrical Sensor, and shifter stub. Optional viper yoke shown in picture available for an additional $190.00 to ease driveshaft fabrication.
================================

The internal information on the ATS is much more specific, however the Ratios are not published.

Any thoughts, or other suggestions?

In the mean time, I will be calling these companies for more information.

Thanks,

Ty --

I put in a Richmond 5 speed in a Camaro I owned... it was without a doubt the worst transmission I've ever owned and that would include a top loader Ford in a 56 pickup. That damn thing was just junk! Seriously. It shifted like a truck transmission and there was no way of adjusting it to make it any better... and it used a LONG brand shifter with nice heim joints etc. It's the internals that made it hard to shift.

SO -- There might just be a good reason why EVERYONE on here uses a TREMEC... ya think??

Just my useless .02 worth...

Yep! I bet that's the truth.

For a POS however, they sure advertise a lot, and evidently sell quite few as well.

I have ZERO experience with them though.

Thanks for the tip.

Larry over at PT has (had?) a Richmond in Motiv8r. In one of his vids he montioned it was top of the list to change out. Watching him shift the thing made me stay away from it.

Just a guess, but I think they sell alot due to price and some Nascar reference?

Ty -- what is the current trans you are looking at replacing and what is the power rating that you feel you are exceeding? They are often very conservative and many have proven (the TKO 600 for example) to be very okay with hundreds of horsepower more put behind them.

[ProdigyCustoms]

Larry's transmission is junk.

You need a T56 Magnum, best shifting transmission at a resonable budget and will handle 700 LB FT TQ. And i have pushed them WAY beyond that 700 mark

Thanks for the feedback everyone.

I currently have a 3550 (I think) I don't have my notes with me, but I know it is the light Duty 5 speed.

Since I am building a 1969 Camaro and a 1964 Vette, I bought a Keisler Road and Track (T-56) for one, (I really think they are cool) and I will buy either a TKO-600 if I put the R&T into the Camaro as it has 600+ Hp, and the TKO-600 will Fit the Vette Console if I use one). If I put the R&T in the Vette, I am thinking about the T-56 Magnum for the Camaro, and just not use a console in the Vette. More than likely I wouldn't use the console anyway because it is the "Grand Sport Model by Mid-America", that I'm putting together and console look silly in them. The TKO will also fit the Trans Tunnel without any modifications, where the T-56 requires some modification in the Vette.

Thoughts?

If you don't already have a TKO 600... don't get one now. Wait a couple months and get the new RS600. That is essentially replacing the TKO 600 for the same approx price.

Flash:

Thanks for the information.

Any Idea what the difference is between the two?
